Site-to-Site VPN with Cisco 891F routers

[igor]

Hi all

I'm new to Cisco world and just finishing CCNA with little experience in Cisco devices so any advice would mean the world to me.

I was given a task to create Site-to-site VPN with two Cisco 891F routers. The problem is that one site has a static IP address while the other has a dynamic one. 

Also the setup has to deliver a remote access to VPN using Cisco VPN Client or AnyConnect software.

My question is: Is this kind of connection even possible with these routers and if not, what kind of additional equipment do I need?

                         Can I configure the router that is installed on the site with dynamic IP to work with the free DNS services like no-ip?

                         Can this kind of setup (if it's even possible) accept adding a third router with static IP in the future?

With best regards

Hi

this is how you build a lan to lan IPsec tunnel between 2 800 series and yes they support it with a security license , you really should have static both ends ,I have not done it before without static so I cant over advice on that end of things but I I provided a doc on it , 1700 setup is same as 800 setup in ios , by the way this will half the throughput of your link when IPsec is enabled due to overhead
